Make sure you continually have your elemental resistances at 75*
Chaos is important somewhat, late game and when your more experienced is when I'd suggest building it up aswell.
Grab a goldrim leathercap with 40 all ele res roll and some other leveling unique items like others have stated and you should be good for a bit. Kitava will reduce your resistances each time you defeat her for for the first time, she has 2 phases.
Goodluck with your playtime.
